Both SDK 0.10.0-beta2 and the ARM gcc 2018q2 run into a build issue with
newlib and conflict definitions of mode_t type.
First we need to add some ifdef protection if mode_t is already defined
and set _MODE_T_DECLARED if we are the first to define it.
Secondarily, we rename include/posix/sys/types.h to
include/posix/posix_types.h so that we aren't getting a name collusion
with the system sys/types.h and that we can easily and clearily include
it (which we need to do to pull in the info from newlib).

Add a private variable `rt_clock_base` that can be used to determine a
real-time clock by using the `k_uptime_get` clock. Once `clock_settime`
is added, this can allow us to have a meaningful real time clock.

Provide an implementation of gettimeofday(). This uses clock_gettime()
with the CLOCK_REALTIME parameter, which is currently unimplemented, but
will allow clients to call this function once this functionality has
been implemented.

Use k_uptime_get() to compute both tv_sec and tv_nsec members
of timespec structure.

Move posix layer from 'kernel' to 'lib' folder as it is not
a core kernel feature.
Fixed posix header file dependencies as part of the move and
also removed NEWLIBC related macros from posix headers.
